Compstegnathus is part of the Chaos Effect line which was released in 1998 after the succes of The Lost World: Jurassic Park. It featured hybrid dinosaurs that were created by mixing the DNA of different species (Jurassic World anyone?). The design of most new sculpts look very sleek, smooth and very colourful. It’s rumoured there was supposed to be a Chaos Effect animated television series, which might explain the cartoon-like look of this toy line.
